Description
Precise ignition timing is non-negotiable in high-performance applications—it’s the difference between maximum power output and catastrophic detonation. The S&S CYCLE Crank Position Sensor (55-1051) is a critical component of the S&S Intelligent Spark Technology system, which continuously monitors engine conditions and automatically adjusts timing to eliminate knock while optimizing both power and fuel economy. If you’re running a carbureted S&S engine and want reliable, intelligent ignition control, this sensor is essential to your setup.
